9/11 truth still in a cloud of smoke?

Eight years after the tragedy of 9/11, questions remain unanswered. A group of experts has convened in Washington to discuss what they think happened. Their theories are in stark contrast to the official version.

The US government said that the World Trade Center buildings collapsed as a result of fires ignited by jet fuel.

But according to members of Architects and Engineers for 9/11 Truth these are lies. The organization is made up of experts and professionals who believe that the real story behind the destruction of the towers is still up in smoke.
